                                In 2018, a study estimated the average adult ingests over 2,000 microplastic particles annually from salt, highlighting the need to find cleaner, purer sources. While most ocean-harvested salts face potential contamination, geographically isolated and ancient geological deposits offer the highest purity standards for health-conscious consumers.
